[Validation of the 13-30ARAMAV assessment, a new quality of life and autonomy questionnaire adapted to visually impaired patients]. / Validation du bilan 13­30ARAMAV, un nouveau questionnaire de qualité de vie et d'autonomie adapté aux patients déficients visuels.

PURPOSE: To evaluate the ARAMAV 13-30 questionnaire, a new autonomy and quality of life questionnaire developed for visually impaired patients. METHODS: We carried out a single-center prospective study at the ARAMAV institute in collaboration with the University Hospital of Nîmes. The patients included were admitted for low vision rehabilitation. Each patient received an occupational therapy assessment, the Short Forms 36 (SF36) quality of life questionnaire and the ARAMAV 13-30 questionnaire at the start and at the end of rehabilitation. We verified the reproducibility, the sensitivity to change, and internal and external consistency of the questionnaire. RESULTS: We included 231 patients over a period of 4 years. All the patients were blind or visually impaired. We observed excellent intra- and interuser reproducibility of the questionnaire, with a Lin coefficient>0.9 (0.99 and 0.91, respectively). By comparing the variations of the different scores between before and after low vision rehabilitation, we observed excellent sensitivity to change for both the autonomy and quality of life portions of the questionnaire. Finally, we observed excellent internal and external consistency. CONCLUSION: We therefore propose the ARAMAV 13-30 questionnaire as a new tool in evaluating autonomy and quality of life specifically in visually impaired patients, which may also be used to assess the effect of low vision rehabilitation.

[Retinal atrophy using optical coherence tomography (OCT) in 15 patients with multiple sclerosis and comparison with healthy subjects]. / Etude de la perte axonale optique en tomographie en cohérence optique (OCT) chez 15 patients atteints de sclérose en plaques et comparaison avec une population de témoins appariés.

INTRODUCTION: Multiple sclerosis is a common disabling progressive neurological disorder. Axonal loss is thought to be a likely cause of persistent disability after a multiple sclerosis relapse. Retinal nerve fiber layer (RNFL) imaging by optical coherence tomography (OCT) seems to be a non-invasive way of detecting optical axonal loss following optic neuritis. OBJECTIVE: To determine whether multiple sclerosis affects retinal nerve fiber layer measurements obtained with optical coherence tomography (OCT3-Carl Zeiss Meditec, Dublin, California, USA). MATERIAL AND METHODS: Diagnosis of MS was based on the MacDonald criteria. The cohort was divided into two groups based on their clinical course (multiple sclerosis with [n=8; 16 eyes] or without [n=7; 14 eyes] optic neuritis antecedents). The disease-free controls were matched for age and gender (n=15; 30 eyes). Retinal nerve fiber layer thickness was measured using optical coherence tomography (OCT; fastRNFL and RNFL thickness software protocol). Visual acuity, visual field, color vision were also noted. RESULTS: There were highly significant reductions (p<0.001) of retinal nerve fiber layer thickness in affected patients (with or without optic neuritis antecedents) compared with control eyes (fastRNFL and RNFL procedures). Visual acuity, visual field and color vision were globally less altered than OCT. There were no significant relationships among RNFL thickness and visual acuity, visual field, or color vision. CONCLUSION: This study has demonstrated the anatomic changes of the retinal nerve fiber layer of patients with multiple sclerosis with optic neuritis antecedents. Thus axonal loss following optic neuritis can be detected with OCT. But the retinal nerve fiber layer of patients without optic neuritis is also thinner than disease-free controls so that chronic optic axonal loss can be frequent in multiple sclerosis. Additionally, OCT was more sensitive than the common ophthalmological explorations to detect optical nerve impairment during multiple sclerosis. Finally, we demonstrated that two procedures fastRNFL and RNFL could be used to detect optic nerve impairment.

The report the main clinical features of such a poisoning and the actual basis of its physiopathology and treatment. According to the four cases reported, they underline the importance of early diagnosis and specific treatment.

[Silent sinus syndrome: a rare case of enophthalmia]. / Le silent sinus syndrome : une cause rare d'énophtalmie.

INTRODUCTION: The causes of spontaneous enophthalmos, without trauma, surgical factors, or systemic illness, which can be found are rare. A particular entity called silent sinus syndrome in the Anglo-Saxon literature, which concerns the long-term effect of hypoventilation of the maxillary sinus responsible for an attraction of the sinus walls, resulting in sagging of the orbital floor, itself responsible for the enophthalmos. CASE REPORT: We report the case about a 29-year-old woman, presenting a left-side spontaneous enophthalmos, with sinus-type pains for 2 months. The clinical examination revealed a horizontal diplopia when looking leftwards. Computed tomography showed a maxillary homolateral sinusitis with characteristic attraction of the sinus walls. The draining of the sinus collection by inferior endoscopic enlargement of the maxillary ostium led to pain resolution. The enophthalmos and diplopia were stabilized. CONCLUSION: After eradicating the orbital causes of enophthalmos, the sinus causes were sought more precisely, the pauci-symptomatic causes such as the silent sinus syndrome. The recognition of this syndrome stopped the progression of enophthalmos by making the maxillary sinus permeable again. A surgical reconstruction of the orbital floor can be proposed in order to correct the motility of the eyes and esthetic considerations.

[Role of acute normovolemic hemodilution in treating retinal venous occlusions]. / Place de l'hémodilution aiguë normovolémique dans le traitement des occlusions veineuses rétiniennes.

The supposed state of retinal venous occlusions by a thrombus has led to the use of diverse antithrombotic treatments (heparin, fibrinolytic agents). This theory being considered at the moment as controversial, haemorheological theories being more particularly favoured, other treatments are proposed in an attempt to better retinal microcirculation, and this by changing the blood viscosity parameters. The study reported here compared the effects on recovery of visual acuity of retinal venous occlusion patients of anticoagulant treatment alone, haemodilution alone, or both together. After initial ophthalmic assessment, twenty-five patients were randomly assigned to one of three groups: group I (n = 5; mean age 62 +/- 14 yr) received heparin for 21 days, followed by antivitamin K drugs for a further 30 days; group II (n = 10; mean age 54 +/- 16 yr) were acutely hemodiluted with 40,000 daltons molecular weight dextran, bringing the haematocrit to between 0.25 and 0.30; on day 2, the same anticoagulant treatment as in group I was associated; group III (n = 10; mean age 58 +/- 18 yr) were only hemodiluted. The hemodiluted state was maintained for 21 days. A biological assessment was carried out for the three groups on days 1, 2, 7, 14, 21 and 30 (haematocrit, fibrinogen level, platelet count, kaolin-cephalin time, heparin level). The evolution of visual acuity was assessed on days 7, 14, 21, 30, 60 and 90. Mean visual acuity was assessed on days 7, 14, 21, 30, 60 and 90. Mean visual acuity was virtually the same for the three groups on day 0.(ABSTRACT TRUNCATED AT 250 WORDS)

[Traumatic bitemporal hemianopsia (author's transl)]. / L'hémianopsie bi-temporale traumatique.

The authors report a case of traumatic bitemporal hemianopsia, without any macroscopic lesion in the chiasma. At this juncture, they argue about the different mechanisms which may occur in the pathogenesis of these lesions, and they dwell on the indirect mechanism of the quartering of the optic nerves, which is responsible for a tear in the chiasma.

[Non-organic visual loss]. / Troubles visuels anorganiques.

Functional or non-organic visual loss is a common problem in neuro-ophthalmologic consultation. There is a mismatch between visual acuity and/or visual field and the relative normality of the clinical examination. It is important to identify these patients so as not to prescribe unnecessary ancillary testing and so as to refer patients for a treatment of a possible psychiatric disorder. Conversely, there are many organic eye pathologies with a normal or quasi-normal fundus. We have at our disposal a large number of clinical and ancillary tests to demonstrate the non-organic nature of the visual loss: clinical examination, orthoptic testing, visual field, electro-physiologic tests. A rigorous diagnostic approach is essential to diagnose non-organic visual loss while avoiding diagnostic pitfalls.

[Cosmetic blepharoplasty complicated by necrotizing periorbital fasciitis: a case report]. / Fasciite nécrosante périorbitaire compliquant une blépharoplastie esthétique : à propos d'un cas.

Necrotizing periorbital or palpebro-orbital fasciitis represents a unique anatomical site for necrotizing fasciitis, which is an extremely rare and very severe, potentially devastating bacterial infection, rapidly leading to facial necrosis with loss of vision and even death of the patient from toxic shock. In this paper, we report a case of necrotizing periorbital fasciitis as a complication of cosmetic lower eyelid blepharoplasty. Necrotizing fasciitis most often affects the upper and lower limbs, the trunk and the perineal area. It is rarely observed in the facial region due to the rich blood supply in this area. The most commonly implicated pathogen is group A, ß-hemolytic "pyogenic"Streptococcus, either alone or in combination with other bacteria, such as staphylococcus or pseudomonas. Mortality varies according to the series and anatomical site. The mortality rate for necrotizing fasciitis is approximately 28 %. It is slightly lower in the periorbital area (15 %). Risk factors for death include alcoholism, diabetes mellitus, immunocompromise, hematologic or pulmonary diseases, and the identity of the causative agent (group A Streptococcus), although approximately 50 % of patients have no predisposing conditions. Management of periorbital necrotizing fasciitis is based on early detection of initial symptoms and on aggressive multidisciplinary treatment including surgical debridement of necrotic areas and antibiotic coverage. The timeliness of treatment and the multidisciplinary approach are considered to be the two essential factors in influencing the mortality and morbidity of this condition.

[Quality of life in patients with wet age-related macular degeneration treated with photodynamic therapy]. / Apport de la photothérapie dynamique dans la qualité de vie des patients atteints de dégénérescence maculaire exsudative.

PURPOSE: To analyze the benefit of photodynamic therapy in terms of quality of life in patients with wet age-related macular degeneration. METHODS: A retrospective study was conducted on 33 patients with subretinal neovascularization receiving visual rehabilitation in a low vision clinic (ARAMAV, Nîmes) in southern France. Twenty had been treated with photodynamic therapy (PDT group) and 13 had not (non-PDT group). In the non-PDT group, the patients had been treated with thermal photocoagulation, transpupillary thermotherapy, or external radiotherapy, or had not received any treatment. Visual acuity, reading speed, reading endurance, and quality of life were compared. Two quality-of-life scales were employed: the VF-14 and NEI-VFQ-25. RESULTS: A significant difference between the two groups in terms of quality of life was observed. The VF-14 score (p<0.01) and two parameters (near activities and distant activities) of the NEI VFQ-25 were significantly higher (both p<0.01) in the PDT group. Visual acuity, reading speed, and reading endurance were similar in both groups. CONCLUSION: Although no difference in terms of functional parameters was observed, photodynamic therapy could preserve the central retina and thus enable a better use of the residual visual function, which could explain the better quality of life perceived by the patients in the PDT group.

[Mucocele of ophthalmologic expression and treatment apropos of 46 cases]. / Mucocèles à expression ophthalmologique et traitement. A propos de 46 cas.

Mucoceles of the facial sinuses are benign tumors. They consist of a pouch made up from altered sinusal mucosa containing mucus ant inflammatory exudate. This tumors have a tendency to distension and to erode the bony walls. Their common site is in the anterior frontoethmoidal, rarely in the posterior ethmoidal or sphenoidal and exceptionally in the maxillary sinuses. They grow progressively at the expense of the eye and its annexes. Standard radiology is the main diagnostic key, but the scanner is essential to determine the extension and to evaluate the integrity of the posterior wall of the frontal sinus. Surgical intervention is the only way to treat a mucocele. The way of access to the mucocele can be either via the inferior way of Jacques or via the superior way of neurosurgical approach.

[A case of post-traumatic occlusion of the central retinal artery]. / A propos d'un cas d'occlusion de l'artère centrale de la rétine post-traumatique.

We report a case of central retinal artery occlusion following a minor ocular injury. The occlusions are an uncommon but well following some surgical operations on the eyeball, the eyelids or the nose. They probably result from an arterial spasm which trigger mechanisms are not very well known.

[Palpebral Merkel cell tumors apropos of 3 cases]. / Tumeurs palpébrales à cellules de Merkel. A propos de 3 cas.

The Merkel-cell tumor is a recently individualized (1972) malignant skin tumor. The diagnosis is made on the pathology. It consists of an intra-dermal proliferation of small regular cells with large nucleus and reduced cytoplasm. The evidence of neurosecretory granules and paranuclear intermediate filaments by electron microscopy is suggestive of a Merkel-cell tumor. Following a review of the literature and 3 personal observations the authors have detailed the clinical, anatomopathologic and evolutional characteristics of palpebral localizations.

Medial canthus (caruncle) single injection periocular anesthesia.

We studied 151 consecutive patients scheduled for elective short-duration ophthalmic procedures to assess the efficacy of an alternative approach to periocular anesthesia. Single injection at the medial canthus was performed with a 25-gauge needle. The studied variables were: injected volume, onset time of the block, akinesia (scored on a 12-point scale), adequate surgical anesthesia (scored on a 5-point scale), and need for reinjection. The injected volume of local anesthetic solution was 8.6 +/- 1.7 mL. The onset time of anesthesia was 6.9 +/- 3.0 min, with an akinesia score of 11.6 +/- 1.1 (maximum 12). Additional reinjections were necessary in 14 cases (9.2%). There was a learning curve for the technique, with 8 of the additional injections being performed in the first 30 patients (26.6%), and 6 in the last 121 (4.9%). The surgical score recorded after surgery was 4.8 +/- 0.6 (maximum 5). There were no complications, including injury to the globe, optic nerve, or retina or orbital hematoma. Medial canthus single injection periocular anesthesia appears to be a promising alternative to the usual double injection peribulbar block.

Ophthalmic regional anesthesia: medial canthus episcleral (sub-tenon) anesthesia is more efficient than peribulbar anesthesia: A double-blind randomized study.

BACKGROUND: Regional anesthesia and especially peribulbar anesthesia commonly is used for cataract surgery. Failure rates and need for reinjection remains high, however, with peribulbar anesthesia. Single-injection high-volume medial canthus episcleral (sub-Tenon's) anesthesia has proven to be an efficient and safe alternative to peribulbar anesthesia. METHODS: The authors, in a blind study, compared the effectiveness of both techniques in 66 patients randomly assigned to episcleral anesthesia or single-injection peribulbar anesthesia. Motor blockade (akinesia) was used as the main index of anesthesia effectiveness. It was assessed using an 18-point scale (0-3 for each of the four directions of the gaze, lid opening, and lid closing, the total being from 0 = normal mobility to 18 = no movement at all). This score was compared between the groups 1, 5, 10, and 15 min after injection and at the end of the surgical procedures. Time to onset of the blockade also was compared between the two groups, as was the incidence of incomplete blockade with a need for supplemental injection and the satisfaction of the surgeon, patient, and anesthesiologist. RESULTS: Episcleral anesthesia provided a quicker onset of anesthesia, a better akinesia score, and a lower rate of incomplete blockade necessitating reinjection (0 vs. 39%; P < 0.0001) than peribulbar anesthesia. Even after supplemental injection, peribulbar anesthesia had a lower akinesia score than did episcleral anesthesia. Peribulbar anesthesia began to wear off during surgery, whereas episcleral anesthesia did not. CONCLUSION: Medial canthus single-injection episcleral anesthesia is a suitable alternative to peribulbar anesthesia. It provides better akinesia, with a quicker onset and more constancy in effectiveness.

Caruncle single injection episcleral (Sub-tenon) anesthesia for cataract surgery: mepivacaine versus a lidocaine-bupivacaine mixture.

UNLABELLED: We compared the quality of anesthesia provided by mepivacaine 2% or a mixture of lidocaine 2%-bupivacaine 0.5%, both with hyaluronidase, in caruncle single-injection episcleral (sub-Tenon) anesthesia. Sixty patients undergoing cataract surgery were included in this randomized, double-blinded study. The time to the onset of blockade, maximal akinesia, need for supplemental injection, and time to recovery were recorded. With mepivacaine, the time to onset was slightly shorter, and the akinesia score higher, than with the mixture. Although statistically significant, these differences are small. With mepivacaine, the time to recovery was shorter. We conclude that the reproducible short duration of the block may be an advantage in outpatient surgery. IMPLICATIONS: We compared the classic mixture of lidocaine 2% plus bupivacaine 0.5% to mepivacaine 2% for caruncle episcleral (sub-Tenon) anesthesia for cataract surgery. Mepivacaine provided a more efficient block with a quicker onset and a quicker recovery. However, these differences were very small and were of little clinical interest.
